RetiredBA/BY, how right you are!
A colleague used to fly his Hawker Fury ISS at Wroughton, The Science Museum people couldn't have been more unhelpful if they'd tried. One of them accused him of flying 'aerobatics' over 'their' aerodrome 'without permission'.... Of course he was well above 500' a.g.l. and Lyneham were perfectly happy.
Eventually he had to move the aeroplane elsewhere due to the attitude of the Museum.
'Dog in the Manger' just about sums up their attitude.
